In theory............

[titan performance]

A small boy has a school home work question to answer, so
he asks his father "Dad, what's the difference between
'theoretically' and 'realistically'?"

His dad thinks and then says "Right-ho son, go and ask your
Mother if she'd sleep with David Beckham for a million quid."

The boy toddles off and comes back saying "Dad, dad, she
said she would! She would sleep with David Beckham for a
million pounds."

"OK son," says his dad. "Now go and ask your sister the same
Question."

The boy toddles off, and comes back saying "Dad, dad, she said
she would too!"

So then his dad says "Right, son, now go and ask your brother if
he'd sleep with David Beckham for a million pounds."

The son comes back excitedly saying "Dad! Dad! He said he would too!"
"Well there you have it, son," said his dad. Theoretically we could
be sitting on three million quid.
Realistically we're living with two tarts and a poof."
